To establish a secure Linux server, you first need to understand the meaning of the configuration files that are related to the network service and how to configure them securely in the Linux environment. In a Linux system, TCP/IP networks are configured with several text fi

Improve Linux Exim server performanceThere are many ways to improve server Exim performance, one way is to use the DNS cache daemon, which reduces the bandwidth and CPU time required to resolve DNS records, and the DNS cache improves network performance by eliminating
Environment: RedHat Linux 5 Enterprise Edition.Xwindows:gnome (Red Hat default installed graphical interface)Although we can use the SSH connection to operate Linux remotely via the character interface, it is inconvenient for more familiar graphics people, so it is necessary to open the Remote Desktop for Linux. There are two popular ways: XDM (X display manager)
Background: If the mobile WAP program is running in Linux, you must use the Windows Proxy Server (HTTP/https) and ISA proxy to access the Internet. Domain name/user name and password are required to use the proxy.
1. First run the command to set the environment variable export http_proxy = http: // 192.168.24.254: 8080/and export http_proxy = http://sywgdev.net/proteinx@192.168.24.254:80 /. But the executi

In today's society, network security is becoming more and more important, especially when we send and receive emails. How can I set up a mail server. We use Red Hat Linux 9.0 as an example. The Linux Mail server suites available in Linux include Sendmail and Qmail. I hope yo

Generally, there are two policies for implementing the firewall function of Linux. One is to completely disable all input, output, and forward data packets, and then gradually enable various service functions according to the user's specific needs. This method is characterized by high security. However, you must fully consider the various service functions required by the user, and there must be no omissions, the system administrator is required to cl
SSH is the abbreviation for secure Shell, developed by the IETF Network Working Group, and SSH is a security protocol based on the application layer and transport layer. SSH is currently a more reliable protocol that provides security for Telnet sessions and other network services. The use of SSH protocol can effectively prevent the information leakage in the remote management process. SSH was originally a program on a UNIX system, and later expanded
① First, we must ensure the absolute security of our servers. I usually set the root password to more than 28 characters, and only a few people must know the root password for some important servers, this is set based on the company's permissions. if a company's system administrator leaves, the root password must be changed. anyone who has been playing linux for a long time should know and change the password.

MySQL is a very common open source database, many users, if you accidentally forgot to install the server's MySQL password, unable to log in, how should I reset it? The method is very simple, now share with you. (System environment: CentOs 6.5 software: Mysql)1. First confirm that the server is in a secure state, that is, no one can connect to the MySQL database arbitrarily. Because the MySQL database is co
